Environmentally sound and sustainable development is the demand of the day. Recognizing its importance, the concept of green technology is advocated through various approaches such as low and no waste technology, environmentally sound technology, waste recycling and utilization, technology with less carbon footprint etc. In this context, utilization of Geosynthetics is gaining ground as it results in less carbon footprint than many of the conventional materials. With this in view, the paper presents a case study which describes the capacity augmentation of a redmud pond using composite reinforced soil struc-ture with high strength geogrids as ‘primary reinforcement’ with due consideration to the hazardous cor-rosive nature of redmud and the locally available red mud as structural fill. For compensating the poor drainage characteristics of red mud, a high performing drainage geo-composite was provided to ensure proper drainage and to dissipate the pore water pressure, which is reported to be performing very well. The utilization of drainage geocomposite instead of conventional gravel filter, where gravel is a nonre-newable natural resource, further helps in the reduction of carbon footprint and to bring the concept of sustainable development.
